I don't know if you have seen a promotional film about the Belt and Road recently released by CCTV. It should be regarded as an advertisement. The duration of the whole film is not very long, no more than three minutes, but the overall ideas and creativity are not like the feeling of traditional CCTV promotional videos. At first, a little boy was playing with a toy train. Then he gently pushed the little train, and it became a bullet train made in China, a Belt and Road country on the right. At this time, the whole picture is divided into two sides. On the right is a little boy in China playing with a small train, and the little girl on the right is connected with a bullet train. Then the little girl threw something, and the picture was divided into two pictures, but the whole short film was connected by the signs of China Belt and Road. I think this advertisement is really creative and accurately expresses the idea of Belt and Road, that is, even people who don't know much about this policy can probably know what China is doing after watching such a film. I think it's really great.
